Since the EGFX Reset Graphics PDU seems to be optional,
the graphicsReset variable (which is updated in that PDU's handler)
should be removed from the rdp_gdi struct with the next change
in public headers (as in freerdp v3).
There are still some clients that expect and check it and therefore
we keep it for now, initialized with TRUE.

To fix#4825 GFX functions must now aquire a lock before accessing surfaces.
This prevents simultaneous update of internal data by client and gfx threads.
Also enforce return value checks, where not already done.
* client/x11: Fix colors on big endian
The bitmaps are recieved in little endian byte order (LSBFirst in terms
of X11). This is a problem on systems, where bitmaps are expected in big
endian byte order (MSBFirst). X11 client tries to handle this situation
by different color formats (e.g. RGBX vs. BGRX), but this doesn't work.
BGRX is not MSBFirst variant of RGBX, it should be XRGB. But this would
work only for 32/24 depths, where color channels matches bytes. Let's
say to the XServer that all the bitmaps are in LSBFirst encoding instead
of changing the color formats on big endian systems.

* client/x11: Fix cursor color on big endian
The cursor color is wrong on big endian systems. It is not probably
possible to force bitmap_order for XcursorImage as it is possible for
XImage. Fortunately, cursors are always 32 bit so we can use ABGR
instead of BGRA to deal with.

* client/x11: Fix comment indentation
The comment has wrong indentation for some reason, let's fix it.
* client/x11: Fix BGR vs. RGB detection
The BGR vs. RGB detection code is leftover from history and I am conviced
that it is wrong with the current color handling, where invert flag is TRUE
by default. However, I suppose that the detection still makes sense and
XServer may use the inverted formats in some cases. Maybe we can force XServer
to use our masks somehow, but let's just fix the value to FALSE now.
* client/x11: Remove unused color shifts
The color shifts are lefover from history and are not used in current
code. Let's remove them.
The H264 context is surface specific, so in multi-monitor (with multiple surfaces)
the decoding was failing. This patch fixes that by introducing a surface specific
h264 context.
The surface's damage region is not relative to the output but
lives in its own universe starting at origin 0,0.
Also fixed the drawing coordinates used in the XRENDER code path
which is used with /smart-sizing
When connecting to windows 8.1 machines the remote RDP server
implementation sometimes sends invalid H264 data. To avoid client
disconnections ignore the broken updates.
Passing True to XSync() discards any pending X11 events. Occasionally
this caused ButtonRelease or KeyRelease to be lost and not forwarded
to the remote computed, leading to stuck keys and buttons.
This should resolve issue #2391
